It's growing and spreading across the wood chipped part of our garden. According to Google Lens it's liverwort, so I've bought Yates Moss and Algae killer, which also lists Liverwort. I've done this twice, but I see very little change. I've also tried generic weed killer.

It's also growing on our footpaths between rocks and that's very hard to get rid off by hand. For other areas I could use garden tools to clear it, I'm aiming to get rid of using weed killers. So it's just for small areas.

Any tips for a weed killer that works on this?

Why would you want to get rid of it?

[–] sylverstream 2 points 1 year ago

Good question! Because I find it ugly & it's taking over the wood chips.

I can't help with the spray, but if that's a mulched area - my go to for killing anything underneath is to put down some plain cardboard on top then drop a good layer of mulch or compost on it. The cardboard will break down with time. I usually do this to kill off grass for new planting areas.

Edit: I looked up the Yates Moss and Algae product and it's just Benzalkonium Chloride which is the same as the green 30 Seconds stuff. You could try a product with a different active ingredient. Like this Kiwicare product: https://www.kiwicare.co.nz/product/lawnpro-mossclear/. Or try with a higher concentration in your sprayer.

The cardboard idea is a good idea. It is an area that used to be a lawn, I removed the grass as it wasn't growing properly. Put on wood chips, but still grass coming through in patches. Will try the cardboard and then new wood chips on top. That should also get rid of the liverwort at the same time. And no chemicals needed, yeah.

You can also use layers of newspaper instead of cardboard, but it breaks down faster and if birds like to dig in that area they'll rip bits of it up. If you do a thick enough layer it still smothers everything underneath though.

I have no idea how you might get rid of it, but it likely grows there because the conditions allow it to thrive. If you kill it, it will probably just come back.

Do you have options in changing the condition? Is it wet and shady, which could be helped by trimming back a tree, or something like that?

Also, roundup/glyphosate can be difficult to get to stick to "slippery" leaves. You can usually add some dishwashing liquid to it to help with that, but soap/surfactants are really bad for insects so try to keep it away from flowers.

Good point. Yeah it's damp / wet there. Not a lot I can do about it. Perhaps I'll just let nature do it's thing here. Thanks.
